Our prototype is comprised of four stages. Each stage is designed to operate at 300kV producing 1.2-MV into 120 Ohms. The pulse length is 25-ns and the pulse-shape is ...

Stream gradient - Wikipedia

High gradient streams tend to have steep, narrow V-shaped valleys, and are referred to as young streams. Low gradient streams have wider and less rugged valleys, with a tendency for the stream to meander. Many rivers involve, to some extent, a flattening of the river gradient as approach the terminus at sea level. Fluvial erosion

Figure 1: Photographs of a cascade reach at high flow (a) and low flow (b) and a step-pool reach at high flow (c) and low flow (d). The arrows indicate the same location on each of the corresponding photographs. Results and Discussion Gradient is a dominant channel characteristic that influences variations in f among all reaches (table 1).

Multi-stage, high-gradient, cyclotron resonance proton ...

Aug 14, 2001· Simulations are presented that show the possibility of high-gradient, high-efficiency cyclotron-resonance acceleration of protons that drift through a cascade of cavities in a uniform axial magnetic field. Means to maintain phase synchronism with a pulsed proton beam are discussed, with resonance frequencies for successive cavities in the cascade lowered by a fixed frequency interval.

Streams and Drainage Systems - tulane.edu

Rapids are turbulent water with a rough surface. Rapids occur where the stream gradient suddenly increases, where the stream flows over large clasts in the bed of the stream, or where there is an abrupt narrowing of the channel. Sudden change in gradient may occur where an active fault crosses the stream …

Stream Processes - Columbia University

Braided Stream patterns are found where there is a very large bed load where there is either a high sediment supply or the stream lies on a loose, unconsolidated bed of sand and gravel. In braided streams the stream does not occupy a single channel but the flow is diverted into many separate ribbons of water with sand bars between.

Low-Flow, Low-Gradient Aortic Stenosis With Normal and ...

Low-flow, low-gradient (LF-LG) aortic stenosis (AS) may occur with depressed or preserved left ventricular ejection fraction (LVEF), and both situations are among the most challenging encountered in patients with valvular heart disease. In both cases, the decrease in gradient relative to AS severity is due to a reduction in transvalvular flow.

late-stage irbc, it imposessub-lytic osmotic stress in younger stage irbc and likely enters these cells [9]. Whether or not exposure of irbc to synthetic chemicals and osmotic stress, respectively, has unwanted conse-quences on parasites remains an open question. In principle, high gradient magnetic separation

Differences in natural history of low- and high-gradient ...

CONCLUSIONS: In patients with AS with high-gradient physiology, the valve constitutes the primary problem. By contrast, low-gradient AS is a systemic disease with valvular, vascular, and myocardial components, resulting in a slower progression of transvalvular gradient, but worse clinical outcome.

Photographic guidance for selecting flow resistance ...

Steps and cascades in high-gradient channels, as well as instream wood, all contribute to increased flow resistance. Submergence of these resistance elements causes enhanced variabil-ity by stage, further complicating estimation procedures. Hence, there is a need for guidance tools for selecting resistance coefficients in high-gradient chan-

Optimized high gradient magnetic separation for isolation ...

In principle, high gradient magnetic separation (HGMS) offers a way to concentrate or deplete malaria irbc from suspensions, relying solely on their intrinsic magnetic properties. Particularly late-stage irbc are known to behave as paramagnetic particles . In a paramagnetic particle, magnetic poles are induced only when exposing the particle to ...

Surface initiation (SNFCO and SDFCO) was related to the high-gradient microstructure in the joint, while IDFCO mainly depended on the size and shape of defects. Retest results showed that it is easier to form IDFCO at −1 stress ratio than 0.1 due to the high stress amplitude promoting stage I crack as well as debonding of inclusion with matrix.

Aortic stenosis - Wikipedia

Aortic stenosis is most commonly caused by age-related progressive calcification (>50% of cases), with a mean age of 65 to 70 years. Another major cause of aortic stenosis is the calcification of a congenital bicuspid aortic valve (30-40% of cases), typically presenting earlier in those aged 40+ to 50+.
